El objeto de la presente invención consiste en un dispositivo destinado para medir variables, como la presión, la temperatura y la turbidez, en relación con un medio líquido, como el agua que utilizan los aparatos electrodomésticos del tipo de lavadoras, lavavajillas, etc., incorporando todos los elementos funcionales para medir las distintas variables en un único conjunto compacto de montaje.The object of the present invention is to a device designed to measure variables, such as pressure, temperature and turbidity, in relation to a liquid medium, such as water used by household appliances of the type of washing machines, dishwashers, etc., incorporating all the elements functional to measure the different variables in a single set compact mounting.
Dicho conjunto constitutivo del dispositivo comprende una envolvente (1) aislante, formada por una capa interior (2) de material rígido y una capa exterior (3) de material elástico, las cuales en la figura 1 se han representado separadas, pero se construyen sobremoldeadas entre si, como se observa en la figura 2, cerrándose dicha envolvente (1) con una tapa (4), sobre la que va integrado un conector (6) en relación con una abertura (5) de comunicación con el interior.Said device constituent set comprises an insulating envelope (1), formed by an inner layer (2) of rigid material and an outer layer (3) of elastic material, which in figure 1 have been represented separately, but are they build overmold together, as seen in figure 2, said envelope (1) being closed with a cover (4), on which it goes integrated a connector (6) in relation to an opening (5) of communication with the interior.
Dentro de la mencionada envolvente (1) se aloja un conjunto funcional (7) constituido por dos circuitos impresos (8 y 9 ó 9.1) en montaje perpendicular uno respecto del otro, yendo en el circuito impreso (8) un sensor de presión (10), mientras que el otro circuito impreso (9 ó 9.1) se dispone atravesando perpendicularmente a ese circuito impreso (8).Within the aforementioned envelope (1) is housed a functional set (7) consisting of two printed circuits (8 and 9 or 9.1) in perpendicular assembly with respect to each other, going in the printed circuit (8) a pressure sensor (10), while the another printed circuit (9 or 9.1) is arranged through perpendicular to that printed circuit (8).
En una realización, según muestra la figura 1, el circuito impreso (9) perpendicular al circuito impreso (8) que incorpora al sensor de presión (10), determina una patilla (17) en la que se dispone un sensor de temperatura (11). Mientras que en otra realización, según muestra la figura 4, el circuito impreso (9.1) perpendicular al circuito impreso (8) que incorpora al sensor de presión (10), determina tres patillas (17.1, 17.2 y 17.3), en dos de las cuales (17.1 y 17.2) se incorporan los elementos (18.1 y 18.2) componentes de un sensor de turbidez, mientras que en la tercera patilla (17.3), que es de distinta longitud que las anteriores, se incorpora un sensor de temperatura (11).In one embodiment, as shown in Figure 1, the printed circuit (9) perpendicular to the printed circuit (8) that incorporates the pressure sensor (10), determines a pin (17) in which has a temperature sensor (11). Meanwhile in another embodiment, as shown in Figure 4, the printed circuit (9.1) perpendicular to the printed circuit (8) that incorporates the sensor pressure (10), determines three pins (17.1, 17.2 and 17.3), in two of which (17.1 and 17.2) the elements (18.1 and 18.2) components of a turbidity sensor while in the third pin (17.3), which is of different length than the above, a temperature sensor (11) is incorporated.
El conjunto estructural de la envolvente (1) formado con las capas (2 y 3) sobrepuestas, determina un cubrimiento aislante del conjunto funcional (7) que cumple con las especificaciones de aislamiento necesarias para la aplicación del dispositivo en medio liquido, presentando la capa rígida interior (2) de dicho conjunto estructural de la envolvente (1) un orificio (14) enfrente de la posición del sensor de presión (10), mientras que la capa flexible exterior (3) determina en relación con ese orificio (14) un cubrimiento (16) a modo de membrana, rellenándose el hueco entre dicha membrana (16) y el sensor de presión (10) con un fluido viscoso (12), como se observa en la figura 3, de manera que la presión externa influye sobre la membrana (16) y se transmite por el fluido viscoso (12) hasta el sensor de presión (10) que acusa y mide esa presión.The structural assembly of the envelope (1) formed with the layers (2 and 3) superimposed, determines a covering functional set insulator (7) that complies with the Insulation specifications necessary for the application of device in liquid medium, presenting the inner rigid layer (2) of said structural assembly of the envelope (1) a hole (14) in front of the pressure sensor position (10), while that the outer flexible layer (3) determines in relation to that hole (14) a covering (16) as a membrane, filling the gap between said membrane (16) and the pressure sensor (10) with a viscous fluid (12), as seen in Figure 3, so that the external pressure influences the membrane (16) and is transmitted by the viscous fluid (12) to the pressure sensor (10) that accuses and measure that pressure.
Para esa función, el fluido viscoso (12) de relleno del hueco entre el sensor de presión (10) y la membrana (16), puede ser cualquier fluido que no sea soluble en agua ni pueda ser arrastrado por ésta, que sea buen aislante eléctrico y que tenga una viscosidad elevada capaz de impedir las fugas entre la capa interior (2) de la envolvente y el circuito impreso (8), pero siendo a la vez capaz de transmitir la presión.For that function, the viscous fluid (12) of filling the gap between the pressure sensor (10) and the membrane (16), it can be any fluid that is not soluble in water or can be dragged by it, that is a good electrical insulator and that has a high viscosity capable of preventing leaks between the layer inside (2) of the envelope and the printed circuit (8), but being At the same time capable of transmitting pressure.
En la parte exterior la envolvente (1) posee unas conformaciones (13) para la sujeción del dispositivo en el montaje de aplicación, determinando dicha envolvente (1) en la parte frontal extrema una protuberancia hueca (15), en la cual se aloja la patilla (17) del circuito impreso (9) que incorpora al sensor de temperatura (11), según la realización de la figura 1.On the outside the envelope (1) has conformations (13) for securing the device in the application assembly, determining said envelope (1) in the part extreme frontal a hollow protuberance (15), in which the pin (17) of the printed circuit (9) that incorporates the sensor temperature (11), according to the embodiment of figure 1.
Cuando el dispositivo incorpora un sensor de turbidez, según la realización de la figura 4, la parte frontal extrema de la envolvente (1) determina dos protuberancias huecas (15.1 y 15.2), en las que se alojan, las patillas (17.1 y 17.2) del circuito impreso (9.1) que incorporan a los elementos (18.1 y 18.2) del sensor de turbidez, mientras que en otra protuberancia hueca de menor longitud (que no se aprecia en el dibujo) se aloja la patilla (17.3) que incorpora al sensor de temperatura (11).When the device incorporates a sensor turbidity, according to the embodiment of figure 4, the front Envelope end (1) determines two hollow protuberances (15.1 and 15.2), in which they are housed, the pins (17.1 and 17.2) of the printed circuit (9.1) that incorporate the elements (18.1 and 18.2) of the turbidity sensor, while in another hollow protuberance of shorter length (not seen in the drawing) the pin is housed (17.3) incorporating the temperature sensor (11).
Para que el sensor de turbidez pueda funcionar correctamente, las protuberancias (15.1 y 15.2) en las que se alojan los elementos (18.1 y 18.2) de dicho sensor de turbidez, se prevén de un material transparente a las radiaciones infrarrojas, pudiendo tener esa condición de transparencia el conjunto de las capas (2 y 3) componentes de la envolvente (1). Alternativamente podría utilizarse también un sistema similar al del sensor de presión (10), dejando por delante de los elementos (18.1 y 18.2) del sensor de turbidez sólo la capa externa (3) de la envolvente y rellenando el interior con gel de silicona u otro medio rígido o semi-rígido transparente a las radiaciones infrarrojas.So the turbidity sensor can work correctly, the bumps (15.1 and 15.2) in which they are housed The elements (18.1 and 18.2) of said turbidity sensor are provided of a transparent material to infrared radiation, being able to have that condition of transparency all the layers (2 and 3) envelope components (1). Alternatively I could also use a system similar to the pressure sensor (10), leaving in front of the elements (18.1 and 18.2) of the sensor turbidity only the outer layer (3) of the envelope and filling the interior with silicone gel or other rigid means or semi-rigid radiation transparent infrared
Según una realización práctica, el conjunto funcional (7) puede incorporar solo un sensor de temperatura (11), disponiéndose éste en el circuito impreso (8), mediante un montaje análogo al descrito para el sensor de presión (10), con un relleno del hueco entre dicho sensor de temperatura y la membrana (16), en este caso, con un gel o elastómero del tipo buen conductor del calor.According to a practical embodiment, the whole Functional (7) can incorporate only one temperature sensor (11), arranging it in the printed circuit (8), by means of a mounting analogous to that described for the pressure sensor (10), with a filling of the gap between said temperature sensor and the membrane (16), in this case, with a gel or elastomer of the good conductor type of hot.
